Burnish head design with multiple pads on side rail
View Patent ↗A disc burnishing head includes an array of burnishing pads and a first and second side rail projecting from a bottom surface of a slider body. The side rails each have an inside surface facing the burnishing pads and an outside surface facing outward. The outside surface of at least the first side rail is serrated. The serrations define a plurality of teeth and notches on the outside surface of the first side rail for cutting, cleaning, and conditioning defects from the surface of a disc.
1. A head comprising:
a slider body having a top surface and a bottom surface; and
a first side rail and a second side rail projecting from the bottom surface, the side rails each having a leading surface, trailing surface, bottom surface, inside surface, and outside surface; wherein the outside surface of the first side rail includes serrations.
2. The head of claim 1 , wherein the outside surface of the second side rail includes serrations.
3. The head of claim 2 , wherein the serrations include teeth and notches on the side rails and wherein the teeth are the shape of rectangular, triangular, polyhedral, or irregular solids.
4. The head of claim 1 , wherein the slider body is substantially rectangular, having a leading edge and a trailing edge, connected by an inner edge and an outer edge defining a longitudinal axis.
5. The head of claim 4 , wherein the side rails are substantially parallel to the longitudinal axis of the head.
6. The head of claim 1 , wherein the head is operably secured to a translator arm.
7. The head of claim 1 , wherein the serrations accumulate loose particles from a disc.
8. An apparatus comprising:
a burnishing head including a slider body, an array of burnishing pads projecting from the slider body, and first and second side rails projecting from the slider body on opposite sides of the array of burnishing pads, the side rails each having an outer surface opposite an inner surface: wherein the first side rail outer surface is serrated;
a rotation mechanism for rotating a disc; and
a translation mechanism for sweeping the burnishing head across a surface of the disc while the disc is rotated.
9. The apparatus of claim 8 , wherein the second side rail outer surface is serrated.
10. The apparatus of claim 8 , wherein the serrated outer surface defines a plurality of teeth and notches.
11. The apparatus of claim 10 , wherein the teeth form rectangular, triangular, polyhedral, or irregular solids.
12. The apparatus of claim 8 , wherein the slider body is substantially rectangular, having a leading edge and a trailing edge, connected by an inner edge and an outer edge defining a longitudinal axis.
13. The apparatus of claim 12 , wherein the side rails are substantially parallel to the longitudinal axis of the burnishing head.
14. A slider comprising:
first and second side rails projecting from a bottom surface of the slider, each side rail having a leading side, trailing side, bottom side, inner side, and outer side; wherein the outer side of the first side rail comprises protrusions.
15. The slider of claim 14 , wherein the protrusions are teeth.
16. The slider of claim 15 , wherein the protrusions are uniform.
17. The slider of claim 15 , wherein the protrusions are non-uniform.
18. The slider of claim 14 , wherein the outer side of the second side rail comprises protrusions.
